Regularly check your tire pressure and inspect the TPMS sensors for damage. Additionally, consider replacing sensors every 5 years or at tire changes to avoid unexpected failures.

What is C1462?

DTC C1462 indicates a malfunction in the vehicle's tire pressure monitoring system (TPMS). This trouble code typically arises when the TPMS control module detects an issue with the pressure sensors. For car owners, this means that the vehicle may not accurately monitor tire pressure, which is crucial for safe driving. If the TPMS isn't functioning correctly, drivers may experience issues such as under-inflated tires, which can lead to reduced fuel efficiency and compromised handling. Additionally, the warning light on the dashboard may remain illuminated, indicating that the system requires attention. Commonly found in vehicles like the 2015-2019 Ford F-150, Dodge Ram, and certain Chevrolet models, this code suggests that a thorough inspection of the tire pressure sensors, wiring, and the TPMS module is necessary. Ignoring this code could lead to more severe tire-related issues over time, making it essential for car owners to address it promptly. Regular maintenance and checks can help prevent such codes from appearing, ensuring that your vehicle remains safe and efficient on the road.

Symptoms

Common symptoms when C1462 is present:

  • Check engine light remains illuminated, indicating a potential TPMS issue.
  • Tire pressure warning light is on, affecting driver confidence in tire safety.
  • Noticeable drop in fuel economy, potentially ranging from 5-10% due to incorrect tire pressure.
  • Uneven tire wear that can lead to costly replacements if not addressed.
  • Possible handling issues or vibrations while driving, especially at higher speeds.

Possible Causes

Most common causes of C1462 (ordered by frequency):

  1. Faulty tire pressure sensor: This is the most common cause, occurring in about 60% of cases. Sensors can fail due to age or damage.
  2. Wiring issues or loose connections: Corrosion or damage to wiring can affect signal transmission, potentially causing a 25% likelihood.
  3. Malfunctioning TPMS control module: Less common but can occur, especially in vehicles with electronic control issues.
  4. Low battery in tire pressure sensors: Batteries can deplete over time, leading to signal loss.
  5. Environmental factors: Extreme temperatures can affect sensor performance, though this is less common.
